                                   AGREEMENT

      1. [***]

<PAGE>

      2.    [ *** ]

      (b)   Subject to sub-paragraph 2(d) below, Owner agrees [ *** ].

      (c)   Subject to sub-paragraph 2(d) below, [ *** ].

      (d)   Once effective, the agreements set forth in sub-paragraphs 2(b) and
      2(c) above shall remain in effect only if the (i) Vendor substantially
      meets all delivery and performance dates set forth in this Amendment, (ii)
      Vendor achieves Substantial Completion of the 1xRTT Upgrades in each
      Upgrade Market within the timeframes set forth in this Amendment, (iii)
      each of the 1xRTT Systems, following completion of their respective 1xRTT

                                       2
<PAGE>
      hereto during their respective remaining Warranty Periods, except for such
      non-compliance which does not materially affect performance or service,
      (iv) all Products, Services and 1xRTT Systems materially comply and
      continue to materially comply with all regulatory requirements set forth
      on Annex III hereto, and (v) Liquidated Damages paid or accrued pursuant
      to Section 18 below do not meet or exceed any Annual Maximum at any time.
      In the event that any of the conditions set forth in the foregoing clauses

      sub-paragraphs 2(b) and 2(c) shall automatically terminate and be of no
      further force or effect.

      (e)   Owner represents and warrants to Vendor that, except as set forth in
      the following sentence of this sub-paragraph 2(e), (i) no Affiliate has
      ever purchased Products from Vendor under the Amended SEPA, and (ii) no
      transfers of Products were made by Owner to any Affiliate. The foregoing
      representation and warranty does not apply to purchases of Products by,
      and transfers of Products to, Cricket Performance 3, Inc. ("CP3"), which
      entity has already been merged with and into Owner and the separate
      existence of CP3 has ceased.

      3.    New Pricing. Vendor hereby extends to Owner the prices for certain
Products and Services as set forth on Annex II hereto. Vendor agrees that the
prices offered to Owner for the Products and Services set forth on Annex II
shall be subject to the terms set forth in Section 5.1(ii) of the Amended SEPA.

      4.    Current Market Upgrades to 1xRTT Products; Substantial Completion.
Vendor agrees to upgrade all Pre-1xRTT Products (as such term is defined in
Amendment #1) in Owner's markets of [ *** ] (collectively hereinafter referred
to as the "UPGRADE MARKETS") with Vendor's [ *** ] Products as described in the
Settlement Agreement (such upgrades the "1XRTT UPGRADES" and the complete
upgraded Systems in such Upgrade Markets the "1XRTT SYSTEMS") with the following
modifications:

      (a)   Notwithstanding Section 5(c) of the Settlement Agreement, the
      required timeframes associated with the 1xRTT Upgrades shall be as
      follows:

            (i)   For each Upgrade Market, Vendor shall achieve Substantial
      Completion of the 1xRTT Upgrade within [ *** ]; and

            (ii)  Vendor shall achieve the installation of CMS11 MSC V5.0 on all
      AXE 10 MSCs in all of the Upgrade Markets [ *** ]. The CMS11 MSC V5.0
      shall provide fully commercial ring tone functionality.

      [***]

      (b)   In addition to the requirements to achieve Substantial Completion
      set forth in the Amended SEPA, in order to achieve Substantial Completion
      of a System (including without limitation 1xRTT Systems), such System
      shall be required to meet or exceed the additional System performance
      requirements as set forth in Annex I and Annex III attached hereto.

                                       3

      5.    Field Retrofit. In addition to Vendor's obligations under Section
5(b) of the Settlement Agreement, Vendor agrees [ *** ] (the "FIELD RETROFIT")
with [ *** ]. Vendor shall begin the Field Retrofit process upon execution of
this Amendment and shall complete the Field Retrofit no later than [ *** ] (such
period the "RETROFIT PERIOD"); provided, however, that the foregoing period
shall be extended on a day-forday basis in the event that either Vendor's
performance is delayed due to the improper actions or inactions of Owner, its
Affiliates or subcontractors, or if Vendor is otherwise permitted an extension
of time pursuant to the terms of the Amended SEPA (e.g. Force Majeure). Owner
agrees to reasonably cooperate with Vendor during the Retrofit Period, including
without limitation, providing reasonable access to the applicable Sites, to
permit Vendor to conduct the Field Retrofit process in a timely and efficient
manner. [***]

      6.    Relocation of RF Remote Units. Vendor shall provide [ *** ]. Vendor
shall be responsible for providing such Services, in conformance with industry
standards, that are necessary for performing said relocation, including without
limitation replacement Products, installation, labor, cranes, construction and
cabling costs and services that may be required for said relocation. [ *** ].
This will include, but not be limited to, the need to add carriers or cell sites
because of the RF performance effect of the relocation of the RF remote units.
In no case shall Vendor be required or responsible for relocating RF remote
units to any Site or location other than the Site where the associated [ *** ]
main unit is presently installed. In the event Owner wants to move such RF
remote units to another Site, Owner shall be responsible for performing said
relocation at its sole cost and expense.

      The schedule and method for the relocation of RF remote units shall be as
mutually agreed upon and shall not necessarily be dependent upon the completion
of the 1xRTT Upgrade or the Field Retrofit. [***].

      7.    Purchase Incentive. [***]

      8.    [ *** ] Swap Out. [ *** ] For purposes of this Amendment, the term
"General Availability" with respect to the Vendor's [ *** ] products means
general availability of the Vendor's [ *** ] products, including without
limitation (i) Interoperability between the Vendor's [ *** ] products deployed
as described in this Section 8 and the [ *** ] main units and the related
[ *** ] remote units deployed in the Upgrade Markets, and (ii) no loss of any
functionality that is generally available with respect to such [ *** ] main
units and the related [ *** ] remote units at the time of the deployment of the
Vendor's [ *** ] products described in this Section 8.

      9.    Field Engineer Support. Promptly, but no later than forty-five (45)
days, after the Effective Date, and for a period of the longer of: (a) twelve
(12) consecutive months, or (b) until both (i) all the [ *** ] products
described in Section 8 above are fully deployed and operating in compliance with
the Specifications therefore, and (ii) the 1xRTT Upgrades in all Upgrade Markets
have achieved Substantial Completion, Vendor shall [ *** ]. The Vendor's field
engineers shall to be granted access similar to Owner's work force in such a
manner as to ensure their maximum effectiveness while at all times maintaining
their status as independent contractors fully within the responsibility of
Vendor. The work methodology of such field engineers shall be mutually agreed
following consultation with Owner's field engineering management.

      10.   Assignment and Assumption. Concurrently with the execution of this
Amendment, Vendor hereby assigns all of its rights and obligations under the
Amended SEPA, as further amended by this Amendment, to Ericsson Inc., a Delaware
corporation ("EUS") located at 6300 Legacy Drive, Plano, Texas 75024. Owner
consents to such assignment, provided that EUS executes the counterpart
signature page set forth below, thereby agreeing in writing to assume all the
covenants, obligations and liabilities of Vendor under the Amended SEPA, this
Amendment and the Settlement Agreement.

      11.   Performance Guarantees. The Substantial Completion of the 1xRTT
Upgrades using the Vendor 1xRTT Specification Compliant Products shall be
subject to the 1xRTT Systems each meeting or exceeding the performance
guarantees as set forth in Annex I hereto, and having the functionality
described in Annex III hereto.

      12.   Failure Mode Analysis. [***].

      13.   Term of Amended SEPA. The Contract Term is hereby extended to
September 19, 2008, unless terminated earlier in accordance with the terms and
conditions of the Amended SEPA, or unless extended by the mutual written consent
of the parties hereto.

      14.   Regulatory Requirements for System Functionality. [***].

      15.   Warranty on Products and Services. Notwithstanding the provisions of
Section 5(d) of the Settlement Agreement, the Warranty Period for all Products
and Services comprising any part of each 1xRTT System (including, without
limitation, 1xRTT Specification Compliant Products) shall extend for [ *** ],
including, without limitation, all Products (including, without limitation, all
Pre-1xRTT Products) that were previously existing in the System prior to such
System being upgraded to a 1xRTT System, except for the primary Vendor mobile
switching center also referred to as the "AXE", with respect to which the
Warranty Period shall extend for [ *** ]. Further, notwithstanding the
provisions of Section 6 of the Settlement Agreement, the Warranty Period in
effect as of the Effective Date for all Pre-1xRTT Products installed in the
Upgrade Markets as of the Effective Date shall expire upon [ *** ] Nothing
herein or in the Settlement Agreement changes the term of the Expansions
Warranty Period, and all of the [ *** ] to be delivered hereunder shall be
deemed to be Expansions.

      16.   Effect on New Purchase Orders. Notwithstanding anything in the
Amended SEPA or the Settlement Agreement to the contrary, including, without
limitation, Section 7 of the Settlement Agreement, Owner shall not be required
to submit any of the New Purchase Orders (as defined in the Settlement
Agreement), and the provisions regarding liquidated damages described in Section
7 of the Settlement Agreement are hereby deleted and of no force or
effect.[***].

      17.   Service Level Agreement. The parties acknowledge that the Service
Level Agreement referenced in Section 11 of the Settlement Agreement has not yet
been negotiated. However, the parties agree to extend the period for the
negotiation and execution of such Service Level Agreement until [ *** ] after
the Effective Date. Such Service Level Agreement shall, upon execution thereof,
replace and supercede Exhibit N to the Amended SEPA.

      18.   Liquidated Damages. The parties agree that damages for Vendor's
delay are difficult to calculate accurately and not reasonably determinable at
the time of execution of this

                                       5

<PAGE>

Amendment, and, therefore, agree that liquidated damages (the "LIQUIDATED
DAMAGES") as described in this Amendment shall be paid for non-performance or
late performance of the Vendor's obligations as set forth in this Amendment for
reasons not otherwise excused by (i) Force Majeure or (ii) Owner's, any
Affiliate's or their subcontractor's (other than Subcontractors as defined in
the Amended SEPA) failure to satisfy its own obligations set out in this
Amendment. For the avoidance of doubt, no payment of Liquidated Damages shall
relieve Vendor from its other obligations under the Amended SEPA, including
without limitation, Vendor's Warranty obligations and the obligation to deliver
and, if required by Owner, install any 1xRTT Specification Compliant Products in
accordance with this Amendment, any SLA obligations, and to remedy any Defects
and Deficiencies in accordance with the Amended SEPA. The parties acknowledge
that Vendor has agreed to the Liquidated Damages in consideration of Owner's
agreement to limit Vendor's total liability as set forth in the Amended SEPA,
this Amendment and the Settlement Agreement. The parties agree that Liquidated
Damages are intended to compensate Owner for the delayed or late performance by
the Vendor and are not a penalty; that the injuries to Owner caused by Vendor's
delays or non-performance described herein would be difficult or impossible to
estimate accurately; and that the amounts payable by Vendor as Liquidated
Damages as specified herein are reasonable pre-estimates of the probable losses
associated with such injuries, and shall constitute Owner's sole money-damages
remedy for such delays or any or all non-performance.

      (a)   [***]

      (b)   [***]

      (c)   Vendor's obligation to pay Liquidated Damages pursuant to Sections
      18(a) and 18(b) is subject to the following annual caps (each an "ANNUAL
      MAXIMUM"):

            (i)   [***]

            (ii)  [***]

            (iii) [***]

            (iv)  [***] In the event of a removal or overlay of a System,
      Vendor and Owner shall work together to provide for an appropriate removal
      or overlay of the System and no interruption of wireless services prior to
      Owner's implementation of wireless service with products furnished by
      another vendor. In consideration of Vendor agreeing to this Liquidated
      Damages provision, along with the other terms and conditions of this
      Amendment, Owner and Vendor further agree that notwithstanding anything to
      the contrary in the Amended SEPA, Owner hereby waives its right now and
      forever to any refund, which it may otherwise be entitled to under Section
      18 of the Amended SEPA or any other provision of the Amended SEPA. [***].

      19.   Full Force and Effect. Except as expressly modified in this
Amendment, the Amended SEPA and the Settlement Agreement shall remain unmodified
and in full force and effect. All references in the Amended SEPA to "this
Contract" or "the Contract" shall refer to the Amended SEPA as amended by this
Amendment.

      20.   Interpretation. In the event of any conflict between the terms of
this Amendment and any exhibit or annex hereto, the terms of this Amendment
shall prevail. In the event of any conflict between the terms of this Amendment
and the Amended SEPA or the Settlement Agreement, the terms of this Amendment
shall prevail. The parties acknowledge that Cricket is currently a party to the
Bankruptcy Cases (as defined in the Settlement Agreement), subject to a
confirmed Plan of Reorganization that has not yet become effective. The parties
agree that the provisions of this Amendment are within the ordinary course of
Cricket's business.
